Injections for Management of PFDs

Share this

Botox toxin A, which is more commonly known for its use in cosmetic surgery, such as reducing facial wrinkles, is also an approved treatment for overactive bladder. Your doctor may recommend Botox injections if lifestyle and behavioral treatments don’t work.

Bulking agents are used to treat both urinary and fecal incontinence. These injections help to reduce involuntary leakage of urine and stool. They work by narrowing the urethra (UI) or the anal canal (FI):

UI bulking agents: Narrow the tube of the urethra to help reduce leakage of urine.

Rectal mucosal bulking agents: By injecting into the rectal mucosa, the mucosa in the area thickens and the anal canal narrows. This causes a slight increase of the pressure in the anal canal and greater resistance to involuntary stool leakage.

As with any medical procedures, there are risks with injections. Ask your doctor to review the risks and benefits of these treatments. Figure out if you are a good candidate before proceeding with Botox or a rectal mucosal bulking agent.
